this proves my pt about why dark pools should be disallowed. all it takes is one person with superior knowledge to destabilize the level playing field. MagTux is the only one who has the complete view of all orders and this is enabled by the dark pools. (this is not an allegation against him at all)
Well, in the spirit of open competitiveness, shouldn't the market decide? If you don't like it, trade somewhere else or start your own exchange. Trading in large volumes with partially open books or not doesn't make a market any less 'stable' or 'gamed'.
I don't know how you can squeak by on 'no offense' when you make a statement like "MagTux is the only one who has the complete view of all orders". So, what are you implying? He's 'working' the book now for his own benefit? I mean, dude, really? It makes no sense. Why would an operator of an exchange do that when the potential risk is lack of trust in his exchange? Nobody would take that kind of risk if they wanted to stay in business, period.
